Question

Fernanda constructed ∠CAB. She then constructed a copy of ∠CAB and labeled it as ∠FDE. Fernanda measures ∠FDE to be 59 degrees. What is the measure of the original angle, ∠CAB, she constructed?
A. The measure of ∠CAB is 118 degrees
B. The measure of ∠CAB is 118 inches
C. The measure of ∠CAB is 59 inches
D. the measure of ∠CAB is 59 degrees

Answer 1

Since Fernanda constructed a copy of ∠CAB and labeled it as ∠FDE, the two angles are congruent. Therefore, the measure of ∠CAB is the same as the measure of ∠FDE.

Given that Fernanda measured ∠FDE to be 59 degrees, the measure of ∠CAB is also 59 degrees.

Thus, the correct answer is:

D. the measure of ∠CAB is 59 degrees.
